ATC 339A35902X 6-Ranger Timing Relay

ATC 339A35902X is a 6-Ranger timing relay designed for plug-in control in industrial automation. This new-old-stock unit operates from 120 V AC at 50/60 Hz, enabling straightforward integration into standard control panels and legacy equipment. The 339 family provides programmable timing actions—on-delay or interval timing—allowing a downstream device to energize after a preset interval or to hold a circuit open for a defined period. As a six-range timer, it offers multiple timing configurations within a compact form factor, built for quick replacement in existing relay sockets. Common applications include sequencing interlocks, coordinating conveyors, or controlling safety circuits where precise delays are required in automation systems. The NOS presentation preserves original performance characteristics for retrofits in legacy control schemes and helps ensure reliable operation in environments that rely on discrete time-delay control.
